Definition of Granulomatosis with polyangiitis

Granulomatosis with Polyangiitis: An uncommon type of inflammation of small arteries and veins (vasculitis) that classically involves the vessels supplying the tissues of the lungs, nasal passages (sinuses), and kidneys.

Granulomatosis with polyangiitis usually affects young or middle-aged adults.

Symptoms include fatigue, weight loss, fever, shortness of breath, bloody sputum, joint pains, and sinus inflammation, sometimes with nasal ulcerations and bloody nasal discharge.

The diagnosis of granulomatosis with polyangiitis is confirmed by finding evidence of vasculitis and abnormal cellular formations called granulomas on biopsy of tissue involved by the inflammatory process.

Granulomatosis with polyangiitis is a serious disease. Without treatment, it can be fatal within months. Treatment is directed toward stopping the inflammation process by suppressing the immune system.
